. ( Obviously soft ) Att -chktm Talking about soft I noticed your pic of a worn front sprocket .Do you run in very dusty/sandy conditions as that was serious and as you said regarding the axle perhaps 'cheese factory' material .
Did the rear wear as bad as it starts getting expensive when having to change both sprockets along with the chain as its pitch will have changed and only mess up the new sprockets
I am able to nitride stuff and may consider going this path if I encounter the same situation

I run in very dusty conditions at the moment Jim. Hoping for rain. That front sprocket had quite a few hours on it before it got to that state lol. They are the most consumable item in the drivetrain but still last better than the VMX used to as there is less load. I've been through one in maybe two or three months. The bike gets used almost daily so quite a few hours worth. Nothing to stress about I just get my money's worth haha. Do you know I've had VMXs since they were released since then I have worn out one ( yes only one ) rear sprocket. I only change the front sprocket and let the chain stretch until the blocks are right at the back. Only a few dollars worth. I don't even change the rear sprocket when fitting a new chain and still get the same life. These aren't real bikes and don't need changing as a set really IMO.

Thanks for clarifying that and sometimes something is designed to wear faster than other sections.
As you say a cheap item
Re the changing as a set on 1;1 I think that it is promoted/suggested to reduce the chance of a chain breaking on differing pitch .Not a nice experiance

Yea I don't think it's a real issue with these bikes . I've never had a chain fail on the big bike but can't imagine it would be pleasant

Speaking of wheelies.
Here's a vid of my wheelie bar doing exactly as you'd want. Stopping the bike from flipping or grabbing and front flipping and bringing the front down in a controlled manner if you get off the throttle. Even over uneven surfaces. No matter what if your front lifts you have to get off it unless you want to keep pulling a wheelie which you can with this setup if you keep on the throttle.http://youtu.be/ZGL6zzGrphw
